Object
   ↳ ComponentActivity
     ↳ FragmentActivity
Known direct subclasses
AppCompatActivity

Base class for activities that wish to use some of the newer platform features on older Android devices.
CarAppActivity

The class representing a car app activity.

Base class for activities that want to use the support-based Fragments.

Known limitations:

  • When using the <fragment> tag, this implementation can not use the parent view's ID as the new fragment's ID. You must explicitly specify an ID (or tag) in the <fragment>.

Summary

Public constructors

Default constructor for FragmentActivity.
FragmentActivity(@LayoutRes @NonNull int contentLayoutId)
